Which method gives accurate value simple pendulum or compound pendulum?

All these factors contribute to the uncertainty in the determining the length of the pendulum in a simple pendulum. In a compound pendulum the point of suspension and point of oscillation are knife edges so are more precisely defined.

Which pendulum provides the accurate value of g?

A compound pendulum has an extended mass, like a swinging bar, and is free to oscillate about a horizontal axis. A special reversible compound pendulum called Kater’s pendulum is designed to measure the value of g, the acceleration of gravity.

Why compound pendulum is preferred than simple pendulum?

In a compound pendulum the point of suspension and point of oscillation are knife edges so are more precisely defined. In a compound pendulum the point of suspension and the point of oscillation are interchangeable ie if point of oscillation becomes point of suspension and vice versa the time period remains unchanged.

Which g value is more accurate?

So once a near equality in time period is obtained on both sides of the centre of gravity of the metallic bar, determining the length of the pendulum becomes more accurate, and so does determining the acceleration g due to gravity.

How does compound pendulum differ from simple pendulum?

The main difference between simple pendulum and compound pendulum is that, in a simple pendulum, the distance between the centre of gravity of the suspended body and the axis of suspension is large compared to the dimensions of the suspended body whereas, in a compound pendulum, the dimensions of the suspended body are …

What is compound pendulum and how it is different from simple pendulum?

Compound pendulum, also called physical pendulum is different from simple pendulum as a simple pendulum is represented by a mass of no size attached to a string of with no mass. A compound pendulum represents a real object that is swinging about a point other than its center of gravity.

Which one provides the accurate value of g Kater’s pendulum bar pendulum simple pendulum?

A bar pendulum has less degrees of freedom than a “ball on a string” type of pendulum, therefore it should be more precise. A bar pendulum is in the form of a rectangular bar. Its length much larger than the breadth and the thickness with holes drilled along its length at equal separation for fixing the knife edges.

What is the value of g in simple pendulum?

Substitute known values into the new equation: g=4π20.750000 m(1.7357 s)2 g = 4 π 2 0.750000 m ( 1.7357 s ) 2 .

What are the disadvantages of simple pendulum over bar pendulum?

The drawbacks of simple pendulum are as follows: a) The simple pendulum can’t have a weightless, heavy point mass bob with inextensible string as we assumed. b) The motion of the bob is not strictly linear. c) The resistance and buoyancy of air affects the motion of the bob which is supposed to be negligible.

What is difference between simple pendulum and physical pendulum?

We have described a simple pendulum as a point mass and a string. A physical pendulum is any object whose oscillations are similar to those of the simple pendulum, but cannot be modeled as a point mass on a string, and the mass distribution must be included into the equation of motion.

What are the differences between g and g?

Differentiate between gravitational constant (G) and acceleration gravity (g)?

Gravitational constant (G)	Acceleration gravity (g)
The value of G = 6.673 × 10-11 Nm2/kg2	The value of acceleration due to gravity of the earth is 9.8 m/s2 and moon is equal to 1.6 m/s2.
The unit of G is Nm2/kg2	The unit of g is m/s2

Why does the value of g vary from place to place?

The gravitational potential at the surface of Earth is due mainly to the mass and rotation of Earth, but there are also small contributions from the distant Sun and Moon. As Earth rotates, those small contributions at any one place vary with time, and so the local value of g varies slightly.

What is the difference between simple pendulum and compound pendulum?

Treating a pendulum as a compound pendulum for calculations is more difficult, but it yields more accurate predictions because the simple pendulum model is idealized. Every physical pendulum is in reality a compound pendulum, because the rod is never massless.

Why is the length of a pendulum more accurate than acceleration?

So once a near equality in time period is obtained on both sides of the centre of gravity of the metallic bar, determining the length of the pendulum becomes more accurate, and so does determining the acceleration g due to gravity. Which method gives the accurate value: a simple pendulum or a compound pendulum?

What is the best way to calculate G using pendulum method?

The second best way to determine g based on the pendulum method would be to use a compound body with a well determined moment of inertia (I). As a matter of fact, the pendulum is an excellent method to predict the moment of inertia for different bodies from the equation below.

What factors affect the period and frequency of a simple pendulum?

The period and the frequency of the compound pendulum depend on the length of gyration, the moment of inertia, and the mass of the pendulum, as well as the gravitational acceleration. • The physical pendulum is the real life scenario of the simple pendulum.
